The paper presents a summary of mineral resources available in the newly formed Telangana state and associated aspects for socio-economic development of the State in time to come. The region was not given much attention in past decades for large scale exploration though it has rich mineral wealth and production is present is limited to coal, limestone, dolomites, quartz, feldspar and building stones. The hidden mineral wealth requires systematic investigations to obtain reliable data on uniform pattern for making policy and plans, through professional agencies in terms of terrain consideration, quantity and quality assessment of the mineral deposits; exploration techniques and its environmental impact assessment; policy and legal framework etc. The recent discovery of uranium is economically very promising which can be utilised for electric power generation. There is a substantial scope for other premier minerals like zinc, base metal sulphides, and platinoid group in the State. The coal deposits need to be further investigated for CBM and gasification. Investigations are vital to discover new deposits in Telangana with existing mineral occurrences as path finders, in light of modern technology. It is suggested to set up mineral based industries/plants, such as fertilizer, cement and calcium carbide, coking plants, refractory and abrasive units and cutting and polishing units for state’s socio-economic growth.
|Mineral Resources, Telangana, Sustainable development, Mining, Management.|
|Minerals are of great economic value and have occupied a characteristic place amongst all the economic resources. Minerals and mineral industries have significant macro links with the economy of a country. Mining activity generates employment opportunities; is obviously an important source of tax revenue and contributes to national income thereby leading to economic growth. In view of the significance minerals-hold in Telangana, the paper makes an attempt to list out all the mineral occurrences of the State and the way forward for socio-economic growth.|
|The newly separated Telangana state from the state of united Andhra Pradesh has a unique geological set up that can host a variety of mineral deposits of economic value. The state Telangana has an area of 112955 Sq.Km, bounded by N latitudes 15o 46’ and 19o 47’and E longitudes 77o16’ and 81o43’ (Fig.1). Though several public organizations have discovered various mineral deposits, still there exists a huge scope for further detailed exploration in search of new mineral deposits in the state and involvement of private/multinational companies has been started just in the last decade. There is significant mineral potential that still lay untapped in Telangana for the growth of mining industry. Now that a separate State has been formed, a systematic regulatory and administrative procedures, infrastructure facilities leading to sustainable exploration and mining activity needs to be formulated. The challenges like lack of sufficient water storage systems, infrastructure etc. have limited the overall investment in mining and exploration activities in the state for the past few decades.|
II. LITERATURE SURVEY
|Several organizations have extensively worked to identify mineral occurrences in this part of the country. Amongst all, work carried out by Geological Survey of India (GSI) is of pioneering importance in discovering a variety of mineral deposits. The first report published by GSI in 1975 describes all the minor and major mineral occurrences in the undivided Andhra Pradesh. This edition was modified and released in 2005 by GSI. These publicly available reports are used to extract information relevant to frame this article. Also reports published by academicians and other public organizations were gathered from open web sources.|
III. REGIONAL GEOLOGY
|Geologically the State, Telangana is endowed with various rock tyes belonging to Archean to Quaternary age. Major part of coal-bearing Pranhita-Godavari Gondwana sedimentary sequence is distributed in this state and the rest is occupied by igneous-metamorphic hard rock terrain. A generalized geological map with mineral occurrences is shown in Fig 2.|
IV. MINERAL RESOURCES
|The following sections deal with various metallic, non-metallic and radioactive mineral occurrences encountered in the State (GSI, 1975 and 2006).|
|Chromite: In the Khammam district the mineral occurs mostly as float ore. Though at places it is noticed in situ in the form of lenticular pockets in ultrabasic rocks like pyroxenite, serpentinite etc. In localities near Bhimavaram (16o 56′ 80o 31′), Gauraram (16o 47′ 78o 36′), Jannavaram (17o 20′ 80o 24′), and Imamnagar (17o 22′’ 80o 28′) and Enkuru (17°18' 80°26'), a total of 2,500 tonnes of float and few hundred tonnes of in situ ore are estimated for these occurrences. This area deserves further exploration not only for chromite but for minerals of platinoid group.|
|Copper: Copper mineralisation is observed in the Mailaram area (17o 43′ 80o 37′) of Khammam district in Dharwar quartz-chlorite schist’s, intruded by grey and blue quartz veins with Cu% between 1.5-1.7. Chalcopyrite occurs as disseminations and stringers associated with pyrite and pyrrhotite. As per GSI the zone of copper mineralisation extends for a strike length of 800 m with a reserve of 0.814 metric tonnes. At Venkatapuram (17o 46′ 80o 45′), chalcopyrite associated with pyrite and pyrrhotite is observed in minor veins of quartz traversing the Pakhal quartzites and dolomites and in the quartz-chlorite schists of the Dharwars holding a mineralised zone ranging in thickness from 1.5 to 5.30 m. for a strike length of 200 m. The Cu content ranges from 0.64 to 1.58 per cent. Indications of sparse Cu mineralisation are also noticed near Banjar (17o 48′ 80o 39′), Mainkawaram (17o 29′ 80o 20′), Rabingudem (17o 30′ 80o 23′), Sarkal (17o 43′ 80o 42′) and Yellambailu (17o 41′ 80o 40′). In current scenario of copper metal prices, this area deserves further exploration with advanced technology.|
|Gold: Alluvial gold is said to have been worked from near the confluence of Kinnerasani river with the Godavari in the Khammam district and also near Mangampet (18o 15′ 80o 30′) in the Warangal district. Of late, exploration activity by GSI is being carried out to test the gold potential in Atkur Block, Gadwal Schist Belt, Mahbubnagar district (GSI, 2011).|

In the Khammam district iron-ore deposits exist between Cheruvupuram, Bayyaram and Navapadu (17o 21′ 80o 10′) and Kothagudem (17o 53′ 80o 04′). These are broadly classified into iron-ore associated with Pakhals and iron-ore associated with banded-hematite quartzite of Dharwar age. The deposits of first group are richer and larger. The total reserve in this area on the basis of a preliminary investigation has been estimated at 11 million tonnes. The hill 1905 about 5 km. north of Bayyaram (17o 35′ 80o 06′), contains two bands of high grade iron-ore one of the bands having an average thickness of 6 m. is estimated to contain 1,06,000 tonnes of high grade ore and 6,00,000 tonnes of low grade ore. The other band with an average thickness of about 15 m. is estimated to contain 72, 60,000 tonnes of all grades of ore. Along the northern flank of the hill, reserve of 6,25,000 tonnes of high grade ore and 3,12,000 tonnes of low grade float ore is estimated. Detrital iron-ore occurs near Ramagundal (17o 39′ 80o 08′), Hematite-quartzite suitable as ironore is present in the Motala-Timmapur area (17o 41′ 80o 07′).|

Mines & Geology department has identified 11 special mining zones exclusively for eco-friendly dimensional stone mining (Phani & Balamurugan, 2014).|
|Clays: White clay suitable for making low grade potteries occur within the Kampthis and upper Gondwana sediments at Panchagoan and Ralapet (19o 19′ 79o 29′) and Katterala (19o 20′ 79o 13′) villages of Adilabad district. A reserve of 5 metric tons of clay is estimated here. Sizeable deposits of clay suitable for the manufacture of porcelain-ware occur near Hyderabad city, about 3.2 km. west of Golconda fort and south of the Kutubshahi tombs. White residual clay is reported from Shekapur village (17o 37′ 77o 37′) of Medak district. Small pockets of white clay are also present at Gambirpet in the same district. In the Nalgonda district occurrences of clays are reported from Chintriyal (16o 38′ 79o 24′). Highly refractory clay occurrences are reported from Konasamudram (18o 44′ 78o 31′) area in the Nizamabad district.|
|Coal: The Pranhita- Godavari valley is known for its coal reserves for more than a century. Coal bearing Gondwana rocks occupy parts of the Adilabad, Karimnagar, Khammam, Nizambad and Warangal districts. The coal bearing Barakar occurs at numerous localities, but is always overlain by the younger Kamthi sandstones and shales. The Gondwanas, mainly the younger Kamthis occupy an area exceeding 11,000 Sq.Km. in the state, but the exposures of the Barakar are few and far berween. The coalfields of the State have been divided into separate units and they are North Wardha, Asifabad, Tandur, Kanala, North Godavari and Sarangapalli, Chinnur, South Godavari, Kamawaram, Allapalli, Singareni, Kothagudem, Polancha and Sivapuram and being mined by Singareni Colleries Company Ltd., (SCCL). The SCCL has made the estimates of the reserves of coal in their lease-hold areas (Table 1, Richard, 2011). The proposed open-cast and underground extractable reserves are 223.4 and 149.1 respectively (SCCL, 2008). Total district-wise reserves are given in Fig.3. As per Indian Bureau of Mines, reserves as per UNFC standards are given in Table 1.|
|The coal is classified as low rock, non-coking with high ash and high moisture contents. This coal is meta-lignite with a carbon content of 81-82 percent and a hydrogen content of about 5 percent. Production of coal by SCCL in 2013-2014 is expected to be 50.47 Million Tons. SCCL operates 13 open cast and 37 underground mines currently. Additional 3/2 million tonnes of coal is expected to occur outside the leased areas of the SCCL in Bellampalli, Golatomagudem, Chilpur and Paloncha. Currently GSI, MECL and SCCL are carrying out exploration activities in Narayanapuram- Pattayagudem, Pagaderu, Bugga- Khammamtogu sector, Vutasamudram-Venkatapuram area, Khammam district is being prospected (GSI, 2011).|
|Corrundum: Corundum occurs in nepheline synites at Rangapur (17o 26′ 81o 10′) and in ultrabasic rocks at Gobbuguriti (17o 17′ 80o 22′), Near Tadakalapudi (17o 31′ 80o 27′). The mineral is associated with kyanite and fuchsitemuscovite- sericite rock. Occurrence of semi-precious corundum of abrasive variety and rare occurrences of gem variety are observed in the exploration pits at Lakshmipuram where the host rock is sillimanite-corundum schistose rock. At Gobbagurti and Singaraipalem corundum occurs in association with kyanite schists. However, at Lallurgudem corundum occurs as placer concentrations in the upper soil (Narayan and Pavanguru, 2013). In the Nalgonda district corundum occurs around Pedagudem, Timmapur, Lingampalle and Anvalgudem villages of Miryalguda taluk.|
|Diamond: Diamonds have been worked in the past in the Krishna river gravel around Bollaram (16o 04′ 78o 26′), Amargiri (16o 03′ 78o 23′), Somasil (16o 02′ 78o 20′) and Maddimadugu (16o 18′ 79o 08′) in Kollapur and Achampet taluks respectively of Mahbubnagar district. About 29+ kimberlite pipes were discovered by GSI and currently regional exploration in search of new pipes in Koilkonda- Devarakadra block in Mahboobnagar and Rangareddy districts is in progress (Ministry of Mines, 2012). Although Golconda has been the main trading center for diamonds in Nizam's reign but no occurrences of diamondiferous pipes have been reported except few famous alluvial diamond occurrences to date. The 29+ kimberlite pipes discovered by government agencies so far in Narayanpet Kimberlite Field, Mahbubnagar district are reported to be barren. However owing to the fact that within a single pipe, there can be different phases of diamond hosting potentiality, a more comprehensive sophisticated investigation, with the help of modern technology, may give rise to some positive information. GSI is carrying out reconnaissance stream sediment sampling at Amangal, 50km west of Narayanpet, Mahbubnagar district. Of late exploration is being carried out by multinational companies like Rio Tinto in other parts of the State, in Nalgonda and Rangareddy districts. The exploration is in preliminary phase and no positive results were hitherto publicly reported.|

|Of late, extensive exploration work being carried out by Atomic Minerals Directorate for Exploration and Research (AMD) in the undivided State of Andhra Pradesh has located several uranium deposits of unconformity proximal, strata|
|bound and fracture controlled type in the Proterozoic sediments of parts of Cuddapah basin. A promising deposit at Lambapur- Peddagattu, Chitrial, Kuppunur and RV Tanda of Nalgonda district, Telangana is an outcome of this exploration. The U3O8% is 0.02 in this new discovery, which is very much promising and viable for mining with tentative reserves of 1600 tons (Sinha et al., 1994). At Wanaparti, Manabubnagar district, uranium minerals occur as fine dissemination in granite. Secondary uranium minerals oxidised by groundwater form coating along joint planes in granite but not mineable. A rare mineral, Ianthinite was reported for the first time in India by Parihar et al., (Singh, 2013) in granites and quartzites with U3O8% 0.25 and 0.031 at Akkaram, Mahbubnagar districts respectively. Several radioactive U an Th anomalies in the metasedimentary enclaves (Archaean) within granite (Archaean to Early- Proterozoic) have been recorded in parts of Granulite Terrain, Karimnagar district at Peddur and Kottur (18o 22′ 78o 46′) with uraninite mineralization assaying as high as 1.96% and in Kottur up to 0.059% U3O8 with negligible thorium (Som el al., 2010).|
|Production statistics available for 2011-2012 is shown in Tables 4 & 5 (Source: www.telangana.gov.in).|
V. THE WAY FORWARD: SUSTAINABLE MINING, PLANNING & MANAGEMENT
|The pace of development and processes of economic growth depend upon the availability and the extent and intensity of niche resources utilization. The State is blessed with good number of mineral occurrences and has the geological environment for many others. The above listed mineral resources indicate that Telangana is rich in niche resources. Unfortunately only few of these occurrences are exploitable at present, either because of poor survey, or lack of detail information, or not economically viable for extraction. However mere availability of minerals is not sufficient for socio economic development, because mineral exploitation involves various steps.|
|Inviting applications from World class companies & transparency in award of leases.|
|Detailed geological investigations.|
|Planning & Execution of prospecting.|
|Qualitative & Quantitative studies.|
|Selection of mining method|
|Order of magnitude studies|
|Environment impact assessment & Management Plan|
|Mining policy and legal framework.|
|These steps involve a long time and heavy capital investment with modern technical know-how, which may yield results in terms of a potential source of revenue and employment. But there are equal chances of failure also during their economic exploitation. In the present socio-economic circumstances it may not be possible for the State to afford such a luxury at the cost of other priorities of the State. To exploit the Sate’s geological potential for the sustainable development, it is important that scientific and detailed prospecting is to be carried out systematically in the entire geologically conducive mineral bearing area of the State using state-of-the-art techniques in a time bound manner. Minerals being a valuable resource, the extraction of mineral resources located through exploration and prospecting have to be maximised through scientific methods of mining, beneficiation and economic utilisation. For sustainable and environment friendly mining, a zero-waste mining has to be the goal and mining technology will need to be upgraded to ensure extraction and utilisation of the entire run-of-mines in the most efficient and sustainable manner. To achieve both these goals of large scale prospecting and optimal mining, large investments will be required together with the latest technologies in prospecting and mining. As the State develops and mining industry grows, assured availability and proximity of mineral resources will play an important role in giving a competitive edge to Indian industry in general and manufacturing in particular. The multiplier effect of minerals processed into metals on downstream industrialisation cannot be over emphasised. Value addition must, therefore, be actively encouraged to the extent appropriate with the long term development of the mineral sector in the State. However, such value addition will need to go hand in hand with the growth of the mineral sector as a standalone industrial activity.|
|About 13.5% of the world's electricity is being produced by more than 440 nuclear reactors. With global climate change as a high-profile concern, nuclear power is increasingly seen as an indispensable part of the mix. The recent uranium mineral discovery in Nalgonda district should be properly developed in an eco-friendly manner and it can be a future source of electric power. The government has to make necessary economic and environmental legislation for providing better deal in prospecting this mineral wealth for the welfare of the State with private and public sector participation. It will be worthwhile if the investigations are carried out through professional foreign agencies in terms of location, reserves and techno-economic feasibility by creating detailed and authentic database for proper planning and utilization.|
|Few MNCs have been granted reconnaissance permits recently, otherwise exploration by government organisations was limited to reporting only occurrences but no large scale investments on commercial exploration were made. GSI has identified an area of 131662.46 Sq.Km. as an Obvious Geological Mineral Potential (OGP) zone in undivided Andhra Pradesh but only 21151 Sq.Km. falls in Telangana, the remaining area in the State needs to be assessed thoroughly (Fig.2). While Government agencies are continuing to conduct the exploration and survey in their way, the private sector is now the main source of investment in reconnaissance and exploration with modern technologies, for which the State government should liberally invite the world class investors.|
|Telangana state is endowed with a variety of mineral occurrences present in different geological environments. The mining operations are limited to only few principal minerals currently. The need for a well-planned programme of survey and exploration, transparent system in awarding reconnaissance, prospecting and mining permits, management of resources which have already been discovered and those which are in the process of discovery and their optimal, economical and timely use are the matters of vital importance requiring comprehensive planning, adequate funding and coordinated successful execution and setting up mineral based industries like fertilizers, glass, abrasives and refractories etc. Such sort of innovative thought process will definitely help boosting socio-economic growth, by the mineral and mining sector, in the newly separated Telangana state.|
